Title: Data signal providing apparatus for data display system
Inventor: DINITE ROBERT S
IPC: G09G5/18
Filed: 1984-10-17
Granted: 1990-09-25
Abstract: The microprocessor responds to groups of coded signals from the main data processing system. In response to each group of coded signals, the system provides a raster of bit signals from a ROM means, of which bit signals graphically define the text character assigned to the coded set of signals being received. In other words, if eight bits of ascii coded signals are transmitted from the main data processing device, that group of signals causes, in a preferred embodiment, the generation of a raster of 8 to 10 bits from the ROM in the microprocessor. In the microprocessor, ten bytes of data are stored in ROM memory for each possible text character to be shown. The raster of bit signals are block transferred from the ROM of the microporcessor to buffer.
